Then parted is broken. A low-level tool should give low-level access. It also makes certain assumptions that causes it to enforce that the GPT managed space is always an even number of sectors. > When I installed FreeBSD over this partition, the instalation went ok, > but when I reboot, EFI couldn't find fs0 any more.

The issue here is that sysinstall expects a two leveled division. First the disk partitioning (slicing) and then the disklabel partitioning. Under GPT we don't use disklabels anymore by default. The UUID I mentioned has been reserved for GPT based partitioning with disklabels. > Normally MBR contains a fake EFI > partition. > I went back and restored the MBR to it's original form, so that EFI > could look into the GPT.

No. Endianness is always little-endian for GPT.

The first is an UFS partition, the second is a swap partition. Yours should be a disklabel partition. -- Marcel Moolenaar USPA: A-39004 marcel@xcllnt.net To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-ia64" in the body of the message
